I am leaving on a trip. I have read that having access to one's spouse's passwords is a big deal if something bad happens.

If I have two step authentication (I'm using Google Authenticator) how can I ensure my spouse can access my lastpass? Just my password won't do the trick, in this situation.

Would I have to also provide my Google authenticator access info so she can install the app, authenticate, etc?

This all makes me a bit dizzy. LastPass and Google do make life simpler in some ways, but this sounds like a thorny problem. Which, if all this were needed, things would be bad enough without an endless loop of denied access.
